Final answer:
Nissan employs a comparative ad strategy to showcase its luxury sedan's features against those of competing brands, aiming to differentiate its product and sway consumer preference. The correct option is D.
Step-by-step explanation:
When Nissan advertises the performance of its new luxury sedan by showing it side by side with competing brands, it adopts a comparative ad strategy.
This type of advertisement is designed to highlight the differences and perceived superiority of Nissan's products in comparison to its rivals.
Comparative advertising can influence the consumer's choice by making the benefits of Nissan's sedan more apparent concerning the competition, potentially shifting the firm's perceived demand curve to the right, signifying increased demand for its cars.
